A gemstone with no crystal structure is called Amorphous or Non-Crystalline. Examples: * Glass
* Organic gemstones like amber, coral, ivory, jet, tortoise shell, pearl
* Low type zircon
The hardness and density of each gemstone are primarily determined by its mineral composition and crystal structure. Hardness is measured on the Mohs scale, which reflects a mineral's resistance to scratching and is influenced by the types of bonds between atoms in the crystal lattice. Density, or specific gravity, is related to the atomic weight of the elements present in the gemstone and how closely they are packed in the crystal structure. Different combinations of these factors result in the unique hardness and density characteristics of each gemstone.
Amethyst fractures are breaks or fissures in the crystal structure of an amethyst gemstone. These fractures can affect the overall clarity and appearance of the gemstone, reducing its value. It is common for amethyst to have fractures, which are often filled in with other minerals or glass during the gemstone's enhancement process.
You can examine a gemstone's crystal shape by using a polarizing microscope or conducting X-ray crystallography. These methods allow you to view the internal structure of the gemstone to determine its crystal shape accurately.
Yes, the mineral malachite does have a crystal structure.
Yes, aquamarine is a crystal. It is a variety of the mineral beryl, which forms hexagonal crystals with a blue-green color due to traces of iron in its structure. Aquamarine is often used in jewelry and is thought to have calming and soothing properties.

Corundum is transparent as a mineral, especially in its gemstone forms such as sapphire and ruby. The level of transparency can vary depending on the quality and any inclusions present in the crystal structure. In general, corundum is prized for its transparency and clarity when cut and polished as a gemstone.
Amethyst is a variety of quartz, which crystallizes in the trigonal system. Its crystal structure is characterized by a hexagonal arrangement of silicon and oxygen atoms, forming a continuous framework of SiO₂ (silicon dioxide). The purple color of amethyst is due to the presence of trace amounts of iron and other impurities, which can create color centers in the crystal lattice. Overall, its unique structure contributes to its beauty and popularity as a gemstone.

Opal is not classified as a true crystal; instead, it is a mineraloid. Unlike crystals, which have a defined and ordered atomic structure, opal has a more irregular arrangement of silica spheres. This unique structure contributes to its characteristic play-of-color, making opal a popular gemstone despite its non-crystalline nature.
There is no crystal structure.
Yes, the mineral malachite does have a crystal structure.
Yes, aquamarine is a crystal. It is a variety of the mineral beryl, which forms hexagonal crystals with a blue-green color due to traces of iron in its structure. Aquamarine is often used in jewelry and is thought to have calming and soothing properties.
Beryllium's crystal structure is hexagonal.
